#16 Why Triathletes Keep Breaking Themselves on the Run

In this episode of Cartel Coaching, Emz and Tim dig into one of the biggest challenges for endurance athletes: running injuries, how they happen, and how to return to running the right way. They break down why running tends to break people down faster than swimming or cycling, how strength work and biomechanics help, and why recovery, patience, and consistency matter more than chasing pace or round numbers.What we coveredWhy triathletes often get injured when they focus too much on mileage or speedThe role of gym work, strength, and plyometrics in better running performanceHow life stress, underfueling, poor sleep, and load stacking can increase injury riskWhy running injuries often creep up slowly instead of appearing all at onceThe importance of adapting to training load before increasing it againWhy Strava, watches, and “rounding up” sessions can encourage poor training habitsHow to use surface choice, shoe rotation, and pacing more intelligentlyWhen to keep running through a niggle and when to stop immediatelyHow to return to running after injury with a walk-run protocolWhy hopping, single-leg strength, and basic movement tests matter before running againHow to approach race decisions when the A-race goal and current fitness don’t matchKey takeawaysRunning is a one-legged, high-impact sport, so small mistakes show up quickly.The body needs time to learn, adapt, and accept training load.More intensity, more volume, and more fatigue at the same time is a recipe for breakdown.Not every session needs to be “perfect” on the watch.If pain changes your biomechanics, stops improving, or lingers, it’s time to get assessed.Returning after injury should be gradual, structured, and guided by strength and control.Practical advice from the episodeBack off early when a niggle appears rather than pushing through for weeksUse a simple traffic-light system to decide whether to run, rest, or seek helpRebuild with walk-run progressions and strength work before resuming normal runningKeep the long-term goal in mind and protect bigger race plans by being patient nowNotable momentTim and Emz also discuss the mental side of racing and training — especially how hard it is to step back from a goal when motivation is high. Their athlete scenarios show how good coaching sometimes means holding athletes back so they can succeed later.Who this episode is forThis episode is for triathletes, runners, and endurance athletes who:keep getting injuredstruggle to manage training loadare coming back from a break or injurywant to run better without breaking downneed a smarter approach to race prep and recoveryAbout Cartel CoachingCartel Coaching shares practical, honest advice for endurance athletes who want to train smarter, stay healthy, and keep progressing.Come find us Cartel Coaching — Swim.
